Background Selenium is a nonmetal that rarely occurs in its elemental state in nature. It exists in both conductive and non conductive forms. It is toxic in large doses, however it is a necessary nutrient for animals.
Electricity Selenium has the ability to convert a.c. electricty to d.c. electricity. It is used commonly in rectifiers.
Photo Uses Selenium can convert light into electricity, but also shows electrical resistance decreasing with increasing illumination. Selenium is a good candidate in production of photocells, exposure meters, photo copy machines and solar cells.
Photography Selenium is used in the toning of photographic prints. It is also sold as a toner. Selenium's use intensifies the tonal range of photographic images, and also improves permanence of prints.
